How do you make a simple rain gauge?

Making a Rain Gauge

1. Cut the top section off a clear bottle as shown. ...
2. Place several small rocks in the bottom (for weight), then fill the bottle with water to the 0 mark. ...
3. Invert the top of the bottle into to rain gauge to act as a funnel. ...
4. Wait for the next rain and observe and record rainfall amounts.

How is rainfall measured ks1?

They use a thermometer to measure the air temperature, an anemometer to measure the wind speed, a weather vane and compass to work out the direction of the wind, and a rain gauge to measure rainfall. They then record all their results on a computer.

What materials do you need to make a rain gauge?

Materials:

1. Empty two-liter plastic bottle.
2. Scissors.
3. A few handfuls of clean pebbles, gravel, or marbles.
4. Masking tape.
5. Water.
6. Ruler.
7. Permanent marker.
8. Rainy weather.

Who invented rain gauge?

Rain gauges are one of the most ancient weather instruments. The ancient Greeks and people in India were the first known to keep rainfall records, about 400–500 BC. In 1441, Korea invented the first standardised rain gauge, the Cheugugi.

Where should rain gauge be?

Rain gauges should be placed in an open area where there are no buildings, trees, or other obstacles to block the rain. This is also to prevent the water collected on the roofs of buildings or the leaves of trees from dripping into the rain gauge after a rain, resulting in inaccurate readings.

How do you measure rainfall at home?

Here's what you'll need to do:

1. Measure the diameter of the bucket at the level of the rain. ...
2. Measure the diameter of the bucket at the bottom in the same way.
3. Calculate the average of the two diameters.
4. Divide by two to find the average radius.
5. Find the average volume of rain = Depth x radius x radius x 3.14.

What are the uses of rain gauge?

1.3 Rain gauge. A rain gauge is a meteorological instrument to measure the precipitating rain in a given amount of time per unit area. The instrument consists of a collection container which is placed in an open area.

Where does rain come from ks1?

At the beginning of the cycle, sunlight heats up water on Earth's surface. The heat causes the water to evaporate, or to turn into water vapor. This water vapor rises into the air. As the water vapor cools, it turns back into water, in the form of droplets.

How is daily weather recorded?

Meteorologists gather information about the weather from satellites, balloons, and other instruments. They use powerful computers to analyse the collected data, and then, draw weather maps to predict the weather.

How do you record the weather?

Meteorologists use thermometers, weather vanes, rain gauges, barometers, hygrometers and their own eyes. Meteorologists also use something called satellites to help record the weather. A weather satellite is a machine that is in space and goes around the Earth.

Does the size of a rain gauge matter?

What is the size of a rain gauge? It doesn't matter because it is not the volume but the height of the water we measure. For example, on a yearly average, all oceans, lakes, outdoor swimming pools and rain gauges increase by nearly one meter! Click to see full answer.

How rain is calculated?

The standard instrument for the measurement of rainfall is the 203mm (8 inch) rain gauge. This is essentially a circular funnel with a diameter of 203mm which collects the rain into a graduated and calibrated cylinder. ... The top of the rain gauge is 0.3m above the ground.

Are rain gauges accurate?

Rainwise tipping bucket rain gauges have an accuracy rating of 2% at 1.5” per hour. ... The National Oceanic and Atmospheric Association (NOAA) weather observer network, uses manual rain gauges with an 8 inch diameter opening. These are considered the most accurate, but are also more expensive.

How many types of rain gauges are there?

The three major types of rain gauges are the standard gauge, tipping bucket gauge and weighing gauge.

Why is rain gauge placed below the ground?

It is an instrument used for determining the depth of precipitation that occurs over a unit area. Thus, it measures rainfall. ... For the measurement of rainfall, the rain gauze should be placed 30 cm above the ground to prevent the splashing of rainwater.

Can you use a 5 gallon bucket for a rain gauge?

5 gallons is about 2/3 of a cubic foot, and 2 inches is 1/6 of a foot. 2/3 cubic feet divided by 1/6 feet is 4 square feet, so 2 inches of rain falling over an area of 4 square feet is enough to fill a 5-gallon bucket.

Why do rain gauges have funnels?

When one fills up with water, it tips and spills out, and the other comes into place to do the collecting. These little funnels tip each time rainfall amounts to . 01 inches. The tip triggers a signal that is transmitted and recorded.

What does 10 cm rainfall mean?

When poured in a measuring glass cylinder with 10 Sq Cm base, the height will be amplified to 10 Cm but graduation will show as 1 cm; 1 cm will be 1 mm;and 0.1 cm will be 0.1 mm. So rainfall can be measured correct up to 0.1 mm.

How does rain fall?

Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. ... Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice.

How do you calculate rainfall per hour?

If all available is monthly average in mm, take the monthly average and divide by number of hours in that month. So if you had 300 mm in April, take 360 mm/(30 days * 24 hours) = 0.5 mm/hour average monthly intensity. If you knew it rained on only 10 days, the average rate on those days would be 1.5 mm/hour.
